Tija de sillín Syncros Duncan Aero SL

The Syncros Duncan Aero SL Seatpost is a frame-specific carbon seatpost engineered for Scott's Foil aero road platform and the Plasma TT, shaped to match the bike's aero tube profile rather than fitting a universal round post. Syncros builds it from UD carbon in a Superlight layup, bringing weight to 195 grams over a 380mm length while holding a 120kg system weight limit. Its clamp accepts both 7x7mm and 7x9mm saddle rails without an adapter, so most road saddles mount directly, and the design is built for straightforward saddle angle and fore-aft adjustment.

Because the post is shaped to the Foil's seat tube, it keeps the bike's aero lines clean instead of leaving a mismatched round post exposed above a shaped tube. The tradeoff with any frame-specific design is that it only fits the frame it was built for, so it's worth confirming compatibility with your specific Foil or Plasma TT before ordering. It's available in a matte black finish with multiple offset options, so you can adjust saddle position without losing the aero benefit of the shaped profile. For Foil and Plasma TT owners replacing a stock post or adjusting fit, it's a direct swap that keeps the frame's aero intent intact.
